and comparing different chemicals and drugs on learning, It is possible to make new all positive reinforcement operant conditioning learning behavior standardized measurements with only positive reinforcers; One possibility is lever press food of two
flavors, one flavor enhanced, at mice this could be enhanced with standard concentration sweetness and also standard concentration attractive scent (notably there is an opportunity to distinguish between an attractive food scent, and a different scent
attractive to mice, possible a component of the naturally occuring scent of other mice), also a nonfood reward could measure completely different cognitive componets and brain functionality as the nonfood areas of the brain are responding, colored lights
and a euphoric, rapid action at humans stimulus, DMSO droplet with cocaine at nude mice could be a 30 second to 3 minute availableized reward at nude mice, or even be active if a mouses nose touches a DMSO-cocaine soaked sponge, It is even possible that
a maze learning test could be used to find out how accurately sought a pathway, as well as how many moments to get to a “cocaine lounge” where cocaine might be administered as variable reinforcement at doses and frequency, or , amount, or as an
experimental prequel to the actual thing being tested, that are absent interference with the actual drug or other experimental variable being tested.

Noting that nondrugged, not experimental variable exposed mice, previously trained at finding a cocaine lounge, as well as experimental variable: drugged mice trained at finding a cocaine lounge, goes with the ability to find the probability and numeric
methods numbers on mice that: on starting a cocaine lounge maze that has either a cocaine lounge alerting light or scent, or an initiating flavor food pellet that communicates “this is a cocaine longe maze” then the different variable at experiment
drug’s effects could be numerically treated. The avidity and capability of prequel to experiment cocaine lounge mice which are untreated with the test drug (or other new variable) are numerically characterizeable with the measurment of the avidity and
capability measured amounts from similar prequel cocaine lounge experienced mice.

DMSO nose touch pads could work with rewards other than cocaine;





Although nitrous oxide could be a euphoric stimulus for solving a puzzle, it seems like although fun this ius only slightly motivating at humans and perhaps actively nonmemorable
